    Hello,

    I want to setup a Shelly Uni with my old Doorbell.

    The Doorbell only works with 8VAC and the wiring is very simple. Whenever the button is pressed the two green wires make a circuit.

    Is it possible with a Shelly Uni powered by a 12VAC adapter, to read the circuit when the button is pressed?

    I have measured the voltage between the green wires and its 8VAC. When the button is pressed, the voltage drops for a second.

    Is there a pin that can read this behavior?

    Thanks in advance,

    John
